My friend wants to know, is it normal for a man's penis to smell like fish? What is the cause?
It is probable that he is masturbating and not washing afterwards.
He needs to wash with soap and water straight after he cums to avoid this. If he stays clean is should not smell bad at all. This also applies to girls.
However, if washing straight away does not help, it is possible that thrush or another infection may be the cause and should get checked out with his doctor.
Unless you have other evidence please ignore the comments above ref he may be cheating as this is problem is purely down to personal hygeine and can easily happen through just masturbating and not cleaning himself properly afterwards.
Even if one has a partner or wife, it is still very common for both sex's to masturbate and is perfectly normal and healthy.
Only if he doesn't wash it after sex. sometimes that happens after jacking off if he doesn't clean up. does he shower?
Are you sure he isn't cheating on you?
Nah, chill out it happens. I had that same problem. Check out a litle cream called Nodoro. Google it, it works I use it.
Only if he doesn't wash it after cumming. are you sure he isn't cheating? he really ought to cover his tracks better.
Not supposed to. Tell him to take a shower
